Title: New formula: apple-gcc42

Re: 9768 and other discussions, I was thinking about merging homebrew-alt's apple-gcc42 formula into mainline Homebrew.

This formula is slightly modified from the homebrew-alt version - it will refuse to install on pre-Xcode 4.2 machines, and doesn't install any gfortran binaries. Since it won't install on pre-4.2 machines, I didn't make it keg-only - it shouldn't be shadowing much (or anything?). That should be reviewed for potential issues though.
